External Conditions That Affect Brake Performance

TIRES
Tires that have unequal contact and unequal grip on road surfaces cause unequal braking. The following conditions may adversely affect braking performance:
^ Unequal tire inflation
^ Tires are different sizes
^ Tires have different tread patterns

VEHICLE LOADING
A heavily loaded vehicle requires more braking effort. On a vehicle with unequal loading, the most heavily loaded wheels require more braking effort than the other wheels.

WHEEL ALIGNMENT
Misalignment of the wheels, particularly excessive camber and caster, causes the brakes to pull to one side.
